fector? :: Object -> Boolean Returns #t if a given object is a fector, #f otherwise.

make-fector :: Int [ Object ] -> Fector Returns a fector of a specified size. If the fill parameter is given, the locations of the fector are initialised to that object, otherwise their initial values are unspecified.fector :: [Object ...] -> Fector Returns a fector whose initial values are given as arguments.build-fector :: Int (Int -> Object) -> Fector returns a new fector of a given length, where each element is initialised to the value of the given function applied to its index.fector-length :: Fector -> Int Returns the number of elements that are stored in the fector.fector-ref :: Fector Int -> Object Returns the value associated with a given index into the fector. If the index is outwith the range 0 <= index < length, then an &assertion is raised.fector-set :: Fector Int Object -> Fector Returns a new fector equivalent to the previous one except the given index is now associated with a given object. If the index is outwith the range 0 <= index < length, then an &assertion is raised.list->fector ;; Listof(Object) -> Fector Returns a fector initialised with the contents of the given list.fector->list :: Fector -> Listof(Object) Returns a list containing the objects in a given fector.
